Glasgow Cathedral

Scotland's finest example of Gothic architecture survived the Reformation intact, making it one of the few medieval cathedrals still standing in Scotland. The 12th-century building houses the tomb of Saint Mungo, Glasgow's patron saint, in the distinctive lower crypt. The cathedral's blackened sandstone exterior and pointed spires dominate the city's medieval quarter. It ranks among Glasgow's most visited sights, and for good reason - most itineraries include it on day one. Entry is free and 45 minutes to 1 hour gives you a thorough visit.

You'll enter through heavy wooden doors into a space filled with colored light from stained glass windows. Stone pillars stretch upward into ribbed vaulting, and your footsteps echo on worn stone floors as you explore the nave and descend to the distinctive crypt below.

Accessibility: Ground floor fully accessible, but lower crypt requires stairs with no lift access

One of the best-preserved medieval buildings in Scotland with 800 years of continuous worship. That puts it near the top of any Glasgow visit, and it deserves the spot. Combine it with Glasgow Necropolis and George Square - they are close enough to walk between and together make the strongest half-day in Glasgow. Mornings are quieter if you want to take your time. Free entry makes the decision easy - walk in, see if it holds your attention, and leave when you have had enough.

• Visit the lower crypt to see Saint Mungo's tomb - many tourists miss this.
• Climb the adjacent Necropolis hill for cathedral views and city panoramas.
• Free guided tours available on weekdays - ask at the entrance.

Insider tip: The cathedral's nickname 'High Kirk' refers to its elevated position, not its religious importance
